We investigated whether a physiological marker of cardiovascular health, pulse pressure (PP), and age magnified the effect of the functional COMT Val158Met (rs4680) polymorphism on 15-years cognitive trajectories [episodic memory (EM), visuospatial ability, and semantic memory] using data from 1585 non-demented adults from the Betula study. A multiple-group latent growth curve model was specified to gauge individual differences in change, and average trends therein. The allelic variants showed negligible differences across the cognitive markers in average trends. The older portion of the sample selectively age-magnified the effects of Val158Met on EM changes, resulting in greater decline in Val compared to homozygote Met carriers. This effect was attenuated by statistical control for PP. Further, PP moderated the effects of COMT on 15-years EM trajectories, resulting in greater decline in Val carriers, even after accounting for the confounding effects of sex, education, cardiovascular diseases (diabetes, stroke, and hypertension), and chronological age, controlled for practice gains. The effect was still present after excluding individuals with a history of cardiovascular diseases. The effects of cognitive change were not moderated by any other covariates. This report underscores the importance of addressing synergistic effects in normal cognitive aging, as the addition thereof may place healthy individuals at greater risk for memory decline.

In connection with a discovery of oxidic manganiferous and ferriferous precipitations in northern Vermland and north-western Dalecarlia, pH measurements of different waters and chemical analyses of waters and bog ores were carried out. The origin of the different bog ores is dealt with in connection with a discussion of some problems of the geochemistry of manganese and iron.

The advancement of GPS technology has made it possible to use GPS devices as orientation and navigation tools, but also as tools to track spatiotemporal information. GPS tracking data can be broadly applied in location-based services, such as spatial distribution of the economy, transportation routing and planning, traffic management and environmental control. Therefore, knowledge of how to process the data from a standard GPS device is crucial for further use. Previous studies have considered various issues of the data processing at the time. This paper, however, aims to outline a general procedure for processing GPS tracking data. The procedure is illustrated step-by-step by the processing of real-world GPS data of car movements in Borlänge in the centre of Sweden.

Background: Evidence-based practice (EBP) is a process through which research is applied in daily clinical practice. Occupational therapists (OTs) and physiotherapists (PTs) are expected to work in line with EBP in order to optimise health care resources. This expectation is too seldom fulfilled. Consequently, research findings may not be implemented in clinical practice in a timely manner, or at all. To remedy this situation, additional knowledge is needed regarding what factors influence the process of EBP among practitioners. The purpose of the present study was to identify factors that influence the use of EBP and the experienced effects of the use of EBP among PTs and OTs in their clinical work. Method: This was a qualitative interview study that consisted of six group interviews involving either OTs or PTs employed by the Jönköping County Council in the South of Sweden. Resulting data were analysed using content analysis. Results: The analysis resulted in the following categories: “definition of evidence and EBP”, “sources of evidence”, “barriers to acquiring evidence and to using evidence in clinical work”, “factors that facilitate the acquisition of evidence and the use of evidence in clinical work”, and “personal experiences of using EBP”. Basing clinical practice on scientific evidence evoked positive experiences, although an ambivalent view towards acting on clinical experience was evident. Participants reported that time for and increased knowledge about searching for, evaluating, and implementing EBP were needed. Conclusion: Because OTs are more oriented towards professional theories and models, and PTs are more focused on randomised controlled trials of interventions, different strategies appear to be needed to increase EBP in these two professions. Management support was considered vital to the implementation of EBP. However, the personal obligation to work in line with EBP must also be emphasised; the participants apparently underestimate its importance.

Within the aging building stock of Europe, there is great potential of saving energy through renovation and upgrading to modern standards, and to thereby approach the internationally set goals of lower energy use. This paper concerns the planned renovation of the building envelope and HVAC systems in a multi-family house in Ludwigsburg, Germany. Five systemic HVAC solutions were compared, with special focus on two systems: A) Balanced ventilation with HRC + Micro heat pump, and B) Forced exhaust ventilation + Heat pump with exhaust air HRC + Ventilation radiators. Given the predicted heating demand and ventilation rate of the house after renovation, the performance of the two systems was compared, alongside three common systems for reference. Calculations were made using TMF Energi, a tool developed by SP Technical Research Institute of Sweden. Both systems A and B were found to have the lowest electrical energy use together with the ground source heat pump system for the assumed conditions. For other assumptions, including different climate and degree of insulation, some differences between these three systems were noted. Most significant is the increased electrical use of system B for higher heating loads due to limitations in the power available from the heat source, exhaust air, which is dependent on the ventilation rate.

Shear transparent cellulose free-standing thin films can develop iridescence similar to that found in petals of the tulip Queen of the Night. The iridescence of the film arises from the modulation of the surface into bands periodically spread perpendicular to the shear direction. Small amounts of nanocrystalline cellulose (NCC) rods in the precursor liquid-crystalline solutions do not disturb the optical properties of the solutions but enhance the mechanical characteristics of the films and affects their iridescence. Smaller bands periodicity, not affected by the NCC rods, slightly deviated from the shear direction is also observed. NCCs are crucial to tune and understand the film's surface features formation. Our findings could lead to new materials for application in soft reflective screens and devices.
